Application filed October 27,1925. 'Serial No.65,'105.

Be it known that I, JOHN B. BEAUDRY, a

citizen of the United States, residing at 1 Los Angeles, inthe county of Los Angeles and State of California, have invented new and useful Improvements in Rail-Joint Nut Locks, of which the following is a specification. Y

This invention relates to improvements in nut locks for preventing the loosening of nuts on the bolts in rail joints.

The primary object of the invention is to provide a device which can be applied d1- rectl 'to the nut and bolt onany of the conventlonal rail joints now" in use and which will effectively prevent loosening of the nut on the bolt and thus prevent loosening of the rail joint.

A further object of the inventlon is to provide a device'which can be easily, quickly and cheaply constructed, and which can be easil and quickly applied to the nut on the olt of a rail'joint so as to prevent loosening of the nut and at the same time is capable of being easily detached 1f desired for any reason.

With the foregoing and other objects in view which will be made manifest in the following detailed description and specifically pointed out in the appended" claims, reference is had to the accompanying drawings for an illustrative embodiment of the invention, wherein:

Figure 1 is a perspective view of a ra1l joint to which the improved nut lock has been applied, 7

Fig. 2 is a side elevation of a port1on of the rail joint shown in Fig. 1, parts being broken away and shown in vertical section,

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2, I

Fig. 4 is a side elevation, parts being broken away and shown in sectlon, of the bottom part 'of' the bottom block of the Fig, 5' is' an end'elevationof the part shown in Fig. 4:,

Fig. 6 is a side elevation, partsfbeing shown insection of the part shown in Fig. 46'

but taken from the reverse side from that shown in Fig; 4, 7 Fig. 7 is'a vertical section taken onth'e line 77 of Fig. 6 in the direction indicated, Fig, '8 is a view in elevation, portions being shown in section,"of the upper part or upper block of the nut lock taken upon that side' which is fish plate, and

positioned against the 1 Fig;'9 isa bottom plan view of the upper block and may beconsideredas taken in the direction ofthe arrow 9 upon Fig.8.

Referring to the accompanying drawings wherein similar referencecharacters designate similar parts throughout, the adjacent rail ends are indicated at R and R, which have fish plates or side plates F of any conventional construction positioned againsttheir sides. Bolts B extend through the rail ends R and R", thus securing the fish fish plates F and through the webs of'the plates to the rail ends and fastening the rail'ends to each other. bolts employed have heads 10 adjacent a which are squared portions 11 which fitin squared apertures in one of the fish plates. The nuts N are usually squared and are screwed onto the threaded portions 'or- The conventional threaded ends 12 of the bolts B. The usual,

construction is to place a split lock washerbeneath each of the nuts N, so that when the nut is tightened, it is intended that these lock washers keep it from loosenin 'In actual practice, however, it is note that the natural resiliency or spring of the lock washers decreased in the course of time, and it frequently occurs that the nuts do loosen so that it is necessaryto keep track-walkers who continually inspect and tighten these nuts. In the use of the improved lock nut these-lock washers heretofore employed are omitted, and the nuts N are tightened directly against the face of one of the fish plates F, or if found desirable, a conventional washer can be positioned between the nut N nd the fish plate. However, the washer is preferably omitted, so that the threaded end portion 12 ofeach of the bolts B, which projects through and beyond the ,nut N, will be of sufficient length to permit the application of the improved nut lock.

The improved nut lock consists oflower' a as indicated by threads16 upon Fig."'7.' 'In and upper parts orjblocks 13 and 14, which parts are adapted to be secured about the threaded end portion 12 of each-0f the bolts B. 7 On the upper face of the lower block 13' there'is formed a recess: 15 which issemi "cylindrical in form and which is threaded drical recess 17 which is also threaded 1 When the twoblocks are positioned together,
